Cortinarius alboviolaceus, commonly known as the silvery-violet webcap, [2] is a basidiomycete mushroom of the genus Cortinarius native to Europe and North America.
The mushroom is lilac, later yellowing and often becoming whitish/grayish. [3] [4] Its cap is 3–8 cm wide, conical to umbonate, dry, silky, with whitish to pale lilac flesh. [3] [4] The gills are adnate or adnexed, grayish lilac becoming brown as the spores mature and lend their color. [3] The stalk is 4–8 cm tall and .5–1.5 wide, larger at the base, sometimes with white veil tissue. [3] [4] The odour and taste are indistinct. [4]
Similar species include the essentially identical C. griseoviolaceus, as well as Inocybe lilacina. [3] C. camphoratus is similar, but with a foul odour. C. malachius has a grayish cap and, when dry, a scaly surface. [4]
Its edibility is considered unknown by some guides but it is not recommended due to its similarity to deadly poisonous species. [3] At least one guide considers it edible, but not recommended. [5] Conflicting accounts indicate that it may itself be poisonous. [6]
